# GenISys

GenISys splits early-stage bulk-carrier concept design into 20 subsystems and uses a simultaneous conditional denoising diffusion model so each subsystem reads the others' intermediate states at every reverse step, instead of generating them in a fixed order. In a five-fit confirmation at a fixed 5,000-nautical-mile voyage range, the model returned designs that both satisfied the 187 formulated engineering constraints and met a common low-cost target in 55.70% of generation requests, versus 51.10% for the monolithic model and 47.54% for the sequential model, corresponding to 9.0% and 17.2% more qualifying designs with similar estimated transport costs.
